WARNING
MICROMASTER drive inverters operate with high voltages.
When electrical equipment is operated, then specific parts of this equipment are
at hazardous voltage levels.
The following terminals can carry dangerous voltages even if the inverter is
inoperative:
♦ the power supply L/L1, N/L2, L3 resp. U1/L1, V1/L2, W1/L3
♦ the motor terminals U, V, W resp. U2, V2, W2
♦ and depending on the frame size the terminals DC+/B+, DC-, B-, DC/R+
resp. DCPS, DCNS, DCPA, DCNA
Emergency switching-off devices in compliance with EN 60204 IEC 204 (VDE
0113) must remain functional in all operating modes of the control device. When
the Emergency switching-off device is reset, then it is not permissible that the
equipment runs-up again in an uncontrolled or undefined way.
In cases and situations where short-circuits in the control device can result in
significant material damage or even severe bodily injury (i.e. potentially
hazardous short-circuits), then additional external measures or
devices/equipment must be provided in order to ensure or force operation
without any potential hazards, even if a short-circuit occurs (e.g. independent
limit switches, mechanical interlocks etc.).
Certain parameter settings can mean that the drive inverter automatically
restarts after the power supply voltage fails and then returns.
The motor parameters must be precisely configured in order to ensure perfect
motor overload protection.
The drive inverter provides internal motor overload protection according to
UL508C, Section 42. I
P0610 and P0335). The motor overload protection can also be guaranteed
using an external PTC or KTY84.
This equipment is suitable for use in a circuit capable of delivering not more
than 10,000 (Frame Sizes A to C) or 42,000 (Frame Sizes D to GX) symmetrical
amperes (rms), for a maximum voltage of 230 V / 460 V / 575 V when protected
by an H, J or K type fuse, a circuit breaker or self-protected combination motor
controller (for more details see Appendix F).
The drive unit may not be used as 'Emergency switching-off device' (refer to
EN 60204, 9.2.5.4).
CAUTION
Only qualified personnel may commission (start-up) the equipment. Safety
measures and warnings must be always extremely carefully observed and fulfilled.
